Convert HD MKV to LG Ally Verizon Wireless

MKV video[1], also wel-known as Matroska video takes lots of advantages on modern codec. And some users would like to rip Blu-ray movie to MKV or convert AVCHD M2TS recordings to MKV to maximally preserve video quality. Although MKV is more and more popular on computer, and even Windows 7 supports playback MKV video natively, you may find the LG Ally (Verizon Wireless) does not recognize MKV files. This is because MKV is just a container format which can contain various codecs, only a small subset of which (e.g. H.264, Xvid) the LG Ally (Verizon Wireless) can play.
